Introduction to n6000_poap_script.7.1.4.N1.1.tcl Software
The n6000_poap_script.7.1.4.N1.1.tcl is an automation tool designed for Cisco Catalyst 6000/6500 Series switches, implementing PowerOn Auto Provisioning (POAP) to enable zero-touch deployment in large-scale network environments. This Tcl-based script automates firmware validation, configuration file retrieval, and service initialization during device boot sequences.
Compatible with Catalyst 6509-E chassis and Supervisor Engine 720 modules, it supports NX-OS 7.1(4)N1(1) environments. The script was released in Q1 2025 to address DHCP negotiation failures in IPv6-enabled management networks.
Key Features and Improvements

Enhanced Security Framework
- SHA-384 firmware integrity verification
- TLS 1.3 encryption for configuration transfers
-
Dual-Stack Network Support
- Simultaneous IPv4/IPv6 DHCP discovery
- SLAAC (Stateless Address Autoconfiguration) optimization
-
Fault Tolerance
- 3-stage retry protocol for TFTP failures
- Automatic recovery from corrupted image downloads
-
Hardware Validation
- Pre-boot ASIC compatibility checks
- FPGA version verification
